But if the kernel determines where stuff is placed in a struct and the kernel can run both 32- and 64-bit executables, you're still fuct.

That is certainly not the case for Intel processors. Even running under 64-bit kernels; 32-bit processes only use 32-bit pointers.

Plus some weird architectures like AS/400 (relevant for AIX) use 128bit pointers even on 32bit ALUs.

I know naff all about AS/400, but since the original AS/400 hardware was 48-bit; and it has all been 64-bit for the last decade or so; one wonders whether the question is even relevant for such hardware?

In the absence of evidence, opinion is indistinguishable from prejudice.
